Appium - Parallel Execution (Grid)

Hello,

Can any one please help me ,
My nodes are working on hub but when i run my script it shows on hub
13:16:06.657 INFO - Available nodes: [http://0.0.0.0:4725]
13:16:06.657 INFO - Trying to create a new session on node http://0.0.0.0:4725
13:16:06.657 INFO - Trying to create a new session on test slot {maxInstance=1, browserName=Android, version=5.0 .2 , platform=ANDROID}

but in node shows error missing plateformName and shows version name blank i can not recognize that node picking desired capabilities from where
[HTTP] --> POST /wd/hub/session {"desiredCapabilities":{"browserName":"android","version":"","platform":"ANDROID"}}
[MJSONWP] Calling AppiumDriver.createSession() with args: [{"browserName":"android","version":"","platform":"ANDROID"},null,null,null,null,null,null,null,null,null,null,null,null,null]

With 1.5 new features says, you can start multiple sessions in 1 server. Or did i understand badly?

At the moment I'm using 2 emulators in paralel with selenium grid. It works fine but I have to open a new appium server for all emulators I need. So if I want to run with 20 different device emulators, I need to launch 20 appium server, which is not cool. My configuration is like this;

appium -a 172.20.0.196 -p 4723 --session-override --nodeconfig appiumnodeconfig1.json
appium -a 172.20.0.196 -p 4724 --session-override --nodeconfig appiumnodeconfig2.json

appiumnodeconfig1.json:
{
"capabilities": [
{
"browserName": "android",
"version": "5.1",
"platform": "ANDROID",
"maxInstances": 1,
"deviceName": "192.168.56.101:5555"
}
],
"configuration": {
"nodeTimeout" : 120,
"port": 4723,
"hubPort": 4444,
"url": "http://172.20.0.196:4723/wd/hub",
"hub": "172.20.0.196:4444/grid/register",
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"hubHost": "172.20.0.196",
"nodePolling": 2000,
"registerCycle": 10000,
"register": true,
"cleanUpCycle": 2000,
"timeout": 30000,
"maxSession": 1
}
}

appiumnodeconfig2.json:
{
"capabilities": [
{
"browserName": "android",
"version": "5.1",
"platform": "ANDROID",
"maxInstances": 1,
"deviceName": "192.168.56.102:5555"
}
],
"configuration": {
"nodeTimeout" : 120,
"port": 4724,
"hubPort": 4444,
"url": "http://172.20.0.196:4724/wd/hub",
"hub": "172.20.0.196:4444/grid/register",
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"hubHost": "172.20.0.196",
"nodePolling": 2000,
"registerCycle": 10000,
"register": true,
"cleanUpCycle": 2000,
"timeout": 30000,
"maxSession": 1
}
}

The thing is, I want to start only 1 appium server and connect multiple emulators to it. Can I do it and how?
Thanks in advance

Check here www.appiumforbeginners.com89 for Appium Grid concept

Thank you but it doesn't answer my question. Tutorials on the website shows exactly the same configuration with mine. You have to open a server for every node.

But I already got the answer from Jonathan Lipps yesterday. He told me that 1.5 work was the groundwork for that new feature, but the feature itself is not released. I guess we're going to have to wait unfortunately.

Yes you can run by use parallel thread concepts with out use selenium grid

Hi @bhaskar,

After doing everything as I found in the discussions, I was able to launch android app in multiple devices in parallel. But after that, only one device was able to finish the rest of the automation, other devices got stuck right after launching app.

P.S.: I was able to launch apps using session overriding, otherwise I was not able to launch apps in parallel even though different servers were running.

Thanks,
Minar

Hi @pushpank

Can you please share the code.

Thanks
Ravi

hi puspank,

Can i have the sample code,even my app is also getting hang after launch in one of the devices

Hello..
I have successfully configure the setup for parallel execution but while executing the demo it is running in one device...

Need help on Selenium Grid: I am trying executes script on different mobile emulators but i can't succeed . I have tried different tutorials but unable to succeed.

@TuHuynh: Tried but doesn't work. Other script are runnung fine. I have use following procedure
1)Started Hub
2)Started Node
3)try to execute script

Let me know if i am missing anything

I am trying demo example:
Code 1:- CalcExample .java

package example;
import java.io.File;
import libs.BaseTest;
import org.openqa.selenium.By;
public class CalcExample extends BaseTest{

public CalcExample(){
}

public CalcExample(int deviceNum) {
    super(deviceNum);
}

public void performOperations() {

    try
    {
        driver.findElement(By.id("com.android2.calculator3:id/cling_dismiss")).click();
        driver.findElement(By.id("com.android2.calculator3:id/digit5")).click();
        driver.findElement(By.id("com.android2.calculator3:id/plus")).click();
        driver.findElement(By.id("com.android2.calculator3:id/digit9")).click();
        driver.findElement(By.id("com.android2.calculator3:id/equal")).click();
        String num = driver.findElement(By.xpath("//android.widget.EditText[@index=0]")).getText();
        System.out.println("Result : "+num);
        driver.closeApp();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

public void run(){
    File app = new File("C:\\AndroidCalculator.apk");
    String appPath = app.getAbsolutePath();
    createDriver(appPath); // create devices
    performOperations(); // user function
}

public static void main(String[] args) {
    // Create object
    CalcExample calc = new CalcExample();
    calc.execute();
}

}

@bhaskar, @pavan_appium,

Do you guys have any idea?
